BRAKE-ROD HEAD.

Application filed June 11,

rlhis invention relates to brake rod heads and more particularly relates to a novel means for securely moi'lnting a sheet metal head upon a brake rod.

The invention consists in the structural features and arrangement of parts hereinafter described.

lin the drawings Figure Il is a top view of a brake rod eX- trenlity upon which a head is mounted in accordance with the invention;

Figure is a side view of the same, partly in section on line 22 of Figure l.

ln these views, the reference character A designates the brake rod and B a U-shaped sheet metal head terminally carried by said rod for establishing a connection to a part, not shown. ln using' sheet metal for this purpose a difliculty is encountered in that the yolie portion B of the head lachs the thickness requisite to establishment of a strong rigid joint between the head and rod. In the present invention 'this ditliculty is overcome by litting a metal block C, preferably of steel, snugly between the parallel arms of the head B in contact with the yoke port-ion thereof, registering openings being formed centrally in said block and yoke portion for engagement by a reduced end portion D of the rod lli, said openings flaring toward the exposed face of said block. llhe reduced end portion D is upset by any suitable means so as to provide a tapered portion which completely fills the llaring openings in the block and yoke portion and also overlaps to some extent the exposed apertured face of said block. Thus, the block C is securely held in position between the arms of the head and against the yoke portion thereof, while the head is firinl y attached to the rod A. The yole portion of the head seats upon an an- .nular vshoulder E adjacent the reduced end portion D, said shoulder being at the larger diameter end of a gradually tapered enhirnemcnt lll of the rod A extending a short distance Vl'oinsaid head.

Since the block C lits snugly and rigidly lfictwcen the arms of the head B, said block has the eil'ect of an integral portion of said head in restraining the latter from rotation. lly the use of said block, the bearing surface of the head engaged by the upset tapei-ed ond portion D of the rod is very considerably increased over that which is provided by the yoke B alone, so that the ri- 1923.

gidity and strength of the connection is largely increased by the employment of said reinforcing block. Any thrust transmitted from the rod A to the head B (or vice versa) is adequately taken care of bythe anmilar shoulder E against which the head seats. Preferably, the free ends of the arms of the head are formed with registering openings Gr :tor use in establishing a connection to the part which said head engages. lVhat we claim as our invention is z l. The combination with a rod and a U-shaped sheet metal head terminally carried thereby, of a reinforcing block sleeved upon the rod between the arms of said head and abutting the closed end thereof, said rod having an upset portion bearing against the block and holding the block against the head aforesaid.

S2. The combination with a U-shaped sheet inet-al head, of a block inserted between and bearing against the arms of said head and likewise bearing against the closed end of the head, said end and block having a regis` tering opening, of a rod having a shoulder forming a sea-t for said head and having a tapering portion beyond said shoulder en gaging in the registered openings of said head and block retaining the block in the head and retaining the head on the rod.

3. The combination with a U-shaped sheet metal. head, of a block mounted Within said head against the closed end thereof, said end and block having a registering opening flaring toward the exposed face of said block, and a rod having an end portion engaging in said opening and upset to fill the same whereby the block is rigidly held in the described relation to the head and the latter is rigidly secured upon the rod.

4l. The combinationl with a sheet metal hea-d having transverse portions, one of which is formed with an opening, of a block litting in the angle between said transverse portions and having an opening regiss tering with that of said head, and a rod having a shoulder forming a seat for said head and having an upset end portion engaging in the registering openings of said head and block rigidly connecting the block to the head and the head to the rod.

5. A brake rod head comprising a rodV the outer tapered portion and holding the head against the inner tapered portion.

6. A brake rod head comprising a rod having a shoulder intermediate the ends thereof and an upset portion at one end, a substantially U-ehaped head having the base thereof sleeved on the rod between the upsetportion and shoulder, and a block sleeved upon the rod between the base o the head and the upset portion of the rod.

T. In combination, a rod having longitudinally spaced shoulders`r a substantially U-shaped head having the base thereofv sleeved on the rod between said shoulders, and a block sleeved on the rod between the base of the head and one of said shoulders. 8; In combination, a substantially U- shaped head having an aperture in the base thereof, a block between the arme of the U-shaped head having an aperture in alignment with the aperture in the buse, and a rod extending through said aligned apertures having a shoulder' engaging the base of the head and a second shoulder engaging the block.

9. In combination, a rod having a Haring end portion, a head sleeved upon Said 'thu'- ing end portion, a shoulder on the rod non stituting an abutment for said heath and a second abutment inemhei.' for the head heid on the rod by the Haring portion aforesaid.

In testimony whereof we atix our signetures.
